Embodiment 1

[0042] The present invention is a kind of anti-inverting and intercepting device for rain and sewage wells, such as figure 1 As shown, a rain and sewage well anti-inverting sewage interception device, the rain and sewage confluence inlet pipe 30 and the rainwater discharge pipe 40 are relatively arranged in the rain and sewage well, and the rain and sewage confluence inlet pipe 30 and the rainwater discharge pipe 40 are arranged in a staggered manner The sewage drain pipe 10 below.

[0043] like figure 2 As shown, the sewage discharge pipe 10 is provided with a sewage shut-off valve 11, the sewage shut-off valve 11 includes a valve body 111 sealingly connected with the sewage discharge pipe 10, and the upper end of the valve body 111 is sealed with a sealing gland 112 , the center of the sealing gland 112 is sealed and slidably provided with a valve stem 113, the upper top of the valve stem 113 is hinged with the lever 13, the upper top of the valve stem 113 is provided with...

Embodiment 2

[0049] The difference between this embodiment and Embodiment 1 is:

[0050] like Image 6 As shown, the outer wall of the lower end outlet of the elbow 31 provided on the described rain and sewage confluence inlet pipe 30 is fixedly provided with a torsion spring connection seat 35, and the other torsion arm of the provided torsion spring connection seat 35 is fixedly provided with a round Shape diversion plate 36, and the plate surface of established diversion plate 36 is penetrated with the blowdown hole 37 that deviates from the center of circle of diversion plate 36.

[0051] In combination with the specific structure of a rainwater well anti-inverting sewage interception device in the above implementation, a rainwater well anti-inverting sewage interception device is further described below:

[0052] A, sewage discharge stage, in the rain and sewage well of this process, no rainwater enters the rain and sewage well from the rain and sewage confluence inlet pipe 30, and t...

Abstract

The invention relates to a flowback prevention and pollution intercepting device for a rainwater and sewage well. The rainwater and sewage well is relatively provided with a rainwater and sewage confluence inlet pipe, a rainwater discharge pipe and a sewage discharge pipe, wherein the sewage discharge pipe is provided with a pollution intercepting valve, the wall of the sewage discharge pipe is provided with a supporting rod, a lever is arranged at the top end of the supporting rod in a hinged manner, one end of the lever is connected with the travel end of the pollution intercepting valve, water washing plates are arranged at the other end of the lever, and a straight rod is arranged among the water washing plates in a connection manner; a downward bend is arranged at the tail end of therainwater and sewage confluence inlet pipe, the outer wall of the bend is provided with a supporting frame, the supporting frame is provided with a vertical sliding base, a connecting rod is arrangedin the vertical sliding base in a sliding manner, and the lower end of the connecting rod is fixed on the straight rod; a port of the rainwater discharge pipe is provided with a first limiting clamping groove and a hinged base, and the hinged base is provided with a pollution intercepting plate; and the pollution intercepting plate comprises a hinge joint hole, a sealing plate, a limiting bulge, afloating cylinder, a discharge window and a second limiting clamping groove. According to the flowback prevention and pollution intercepting device for the rainwater and sewage well and a working method of the flowback prevention and pollution intercepting device, the sewage is prevented from being mixed into a rainwater system, the pollution intercepting effect is good, the rainwater is prevented from flowing back and entering a sewage pipe network, and the maintenance is easy and the cost is low because of a mechanical structure.

Description

technical field [0001] The invention relates to the technical field of drainage treatment, in particular to a sewage well anti-backflow interception device and a working method thereof. Background technique [0002] Rainwater well is a unified collection facility for urban precipitation. The seepage pipe extending downward at the bottom can replenish rainwater to the ground, and the excess rainwater is drained through the drainage pipe. Its function is to slow down land subsidence and prevent flooding during heavy rain. Soak the road pavement. Sewage wells are drainage wells for urban sewage discharge and sewage. Urban sewage includes: various impurities, dirt, and sewage with mixed components. The rainwater well is a kind of urban public facility that combines rainwater wells and sewage wells. Its advantages lie in that it reduces the cost, cycle and construction difficulty of the project. Due to the special purpose of rain and sewage wells, sewage interception equipment ...
